Lots of links about commenting...
A Blog Around the Clock has a list of links to blog posts about commenting on (scientific) papers.
There have been quite a few posts over the last few days about commenting, in particular about posting comments, notes and ratings on scientific papers. But this also related to commenting on blogs and social networks, commenting on newspaper online articles, the question of moderation vs. non-moderation, and the question of anonymity vs. pseudonymity vs. RL identity.
Read the post to get all the links.
I must admit that I have never left a comment on an online paper. If I blog about a paper, I leave a traceback, but that is as far as it goes.
Since putting a review of a paper on my blog, just to add a comment, is a lot of work, I guess I should just get used to leaving comments instead.
Still, I am reluctant to comment on papers. I don't mind firing off a half thought through comment off at a blog, but I feel that for a scientific paper I should make sure I understand all the details of the paper before I start commenting on it. I guess I just have to overcome that feeling.
